One instead of ten - that's the advantage of HDMI for the transmission of high-definition video and audio signals. If some eight years ago this connector was only equipped with TVs, players, game consoles with SOURCE engine, media centers of the last generation, nowadays it has become a standard. Any modern device for the reproduction of multi-content without hdmi looks like an exhibit of the museum, since from the moment of its appearance in 2003, this protocol for transmitting a high-definition signal, combining quality and saving space, surpassed other standards.
The advantage of connecting a laptop to a TV via an HDMI cable
The undeniable advantage of this cable when connecting the two devices remains the high quality of simultaneous transmission of video and audio, while other types of connection are inferior to it in terms of characteristics. Connect the PC( Lenovo, Asus) to any of the popular home devices - Philips, Sony Bravia, Toshiba - in two main ways: by cable and without wires.
View any content on the big screen with comfort - just by connecting a large plasma screen through the cord. Make a clear signal you can and without viewing the video from YouTube. Securely secure the plug, provided that the two connected devices are equipped with an HDMI jack. If at least one of them does not have such a port, you will have to use other connection standards:
- Via a rectangular connector with bevelled corners VGA( such a port is on the rear panel of each device).With its help, it's easy to transfer to an ordinary( analog) TV an image, but not a sound, so you will need an additional cord for the audio signal.
- RCA input is available on all new TVs, but you can not connect the laptop "through the tulip", because this connector is a rare phenomenon in them. But even if there is a place for a yellow plug in the PC( composite video), you will need to connect headphones to transmit the audio signal.
- You can do without HDMI if you use a USB port and cable. The TV should be equipped with such a connector, and the laptop - be able to connect new equipment, otherwise video playback will be unavailable. There is another option - connection via USB adapter, but for this you need to purchase the Q-Waves Wireless USB AV kit. To an electronic device with a large screen, it connects via a VGA or HDMI port, and the adapter itself is inserted into the PC.This device operates with a limited range of action, so the TV with the laptop should be near.
- Without a cable to connect the laptop to the TV you can wifi if the latter supports this connection and is equipped with a wireless adapter.
Varieties of HDMI cable
To reproduce computer content at the highest quality level, when the connection is conditioned by certain requirements or limitations, it is possible to use different types of HDMI cable:
- Standard. It is the simplest kind, it has a small bandwidth. For home devices, this type of cable is optimal, unless high demands are placed on the quality of video and sound. These properties are significantly affected by the length of the cable, how well the plug is attached, and which video card is installed on the PC.
- Standard with Ethernet. This is an advanced type of cable that provides two-way data transfer, but provided both devices support Ethernet HDMI technology.
- High Speed - the type of cable that provides the maximum resolution, bandwidth and features universal characteristics. With its help it will be possible to connect absolutely any home devices.
- High Speed with Ethernet is a high-quality high-speed cable with an additional data transfer function using Ethernet HDMI technology.
- Standard Automotive is a cord intended for use in vehicles. A significant difference of this type of cable from the previous ones is its resistance to vibrations, since special connectors rigidly fix the connection. Even the newest type of HDMI cable is protected from sudden changes in temperature and high humidity.
